Description

wordexp (and wordfree) Haskell wrapper

Synopsis

wordexp :: Flags -> String -> IO (Either WordexpError [String])
data Flags
nosubst :: Flags
errors :: Flags
noundef :: Flags
data WordexpError

Wrapper

wordexp :: Flags -> String -> IO (Either WordexpError [String]) Source #

wordexp wrapper

Allows to specify desired flags, return expanded strings or encountered error if any

Flags

data Flags Source #

wordexp flags

Not every flag is supported since some of them do not make much sense in Haskell anyway

noundef :: Flags Source #

Do not accept undefined shell variables, treat them as errors

Errors
